Abstract:
In metals, orbital motions of conduction electrons on the Fermi surface are quantized in magnetic fields, which is manifested by quantum oscillations in electrical resistivity. This Landau quantization is generally absent in insulators. Here, we report a notable exception in an insulator—ytterbium dodecaboride (YbB12). The resistivity of YbB12, which is of a much larger magnitude than the resistivity in metals, exhibits distinct quantum oscillations. These unconventional oscillations arise from the insulating bulk, even though the temperature dependence of the oscillation amplitude follows the conventional Fermi liquid theory of metals with a large effective mass. Quantum oscillations in the magnetic torque are also observed, albeit with a lighter effective mass.

Abstract:
The crystal structure of single-crystal Kondo insulator YbB12 was studied at nine temperatures in the range 85–293 K based on X-ray diffraction data. Very weak Jahn–Teller distortions of the cubic lattice were detected at all temperatures, but did not require a revision of the structural model. Heat capacity and electrical conductivity of YbB12 single crystals were studied in the temperature range 1.9–300 K. It is found that both the structural parameters and the indicated physical properties have some specific features in the temperature range 120–160 K. The unit cell of YbB12 contracts when cooled below 160 K and expands at around 120 K. The temperature dependences of the equivalent atomic displacement parameters U eq(T) are no longer monotonic around 140 K and should be modeled by two Einstein curves for Yb and two Debye curves for boron atoms above and below this temperature. As follows from the temperature behavior of the specific heat, coupled oscillations of Yb ions in a double-well potential lead to the appearance of a charge gap in the density of states and gradual deterioration in conductive properties of the crystal below 150 K. This metal–insulator phase transition is accompanied by a kink in the U eq(T) curves and changes in the unit-cell values.

Abstract:
Cette thèse porte sur l'étude par diffusion inélastique de neutrons des propriétés magnétiques de borures de terre rare : ceb#6, prb#6 et ybb#1#2. La difficulté de réalisation des expériences, notamment la faiblesse des signaux due en partie à la forte absorption des neutrons par le bore, nous a conduit à inclure, dans un programme d'analyse, la correction d'absorption. La partie principale de cette thèse a été l'étude des interactions magnétiques dans les phases ordonnées de ceb#6 et prb#6. Nous avons confirmé la présence d'interactions magnétiques quadrupolaires importantes, grâce à la mesure des excitations magnétiques dans la phase quadrupolaire de ceb#6 en appliquant un champ magnétique dont la valeur était comprise entre 0 et 6 t, et dans les phases double-k et simple-k basse température de prb#6. De plus nous avons montré qu'il semble exister une compétition entre les interactions magnétiques quadrupolaires et les interactions magnétiques dipolaires dans le compose ceb#6, alors que les interactions quadrupolaires dans prb#6 semblent au contraire renforcer la structure magnétique dipolaire. Les mesures effectuées avec le compose ybb#1#2 nous ont permis de donner une valeur de 60 k pour l'énergie du gap, cette valeur étant conforme à celles obtenues par des mesures de résistivité et d'optique. De plus nous proposons un schéma de niveau de champ cristallin, avec le niveau fondamental #8 et les niveaux excites #7 et #6 a respectivement 18 et 39 mev. En annexe, nous présentons également les résultats obtenus par diffusion inélastique de neutrons avec le compose bidimensionnel xy bani#2(po#4)#2. Un programme a été développé pour déconvoluer les spectres mesures de la fonction de résolution instrumentale à 4 dimensions. Les largeurs intrinsèques, ainsi déterminées, de la diffusion magnétique critique ne montrent aucune caractéristique des excitations non linéaires prévues par la théorie, mais peut être expliqué uniquement par une renormalisation des ondes de spin
