Analysis of low temperature specific heat data (1.5 K–25 K) in two glasses of the AgI-Ag[sub 2]O-B[sub 2]O[sub 3] system reveals that the temperature dependencies of C[sub p] are in qualitative agreement with the predictions of the Soft Potential Model. It has been also found that a decreasing connectivity of the network enhances the deviations of C[sub p] from a T[sup 3] behavior. © 2000 American Institute of Physics.

    We theoretically investigate the interaction effect between oxygen impurities in crystalline germanium on the basis of a quantum rotor model. The dipolar interaction between nearby oxygen impurities engenders non-trivial low-lying excitations that give rise to power-law specific heats below 0.1...

    Specific heat measurements of the quasi-one-dimensional S = 1/2 quantum spin system (CH3)2NH2CuCl3 have been carried out in a magnetic field up to H=8 T. This compound shows a 1/2 magnetization plateau between 2 T and 3.5 T and the magnetization saturates at H=14 T. We observed field-induced...

    The low temperature specific heat of the colossal magnetoresistance compounds (NdY)CaMnO ( x=0, 0.1) for 0.4≤ T<2 K in magnetic fields up to H=9 T has been studied. Applied magnetic fields lead to the drop of the low temperature specific heat by more than 2 orders, which implies a large...
