We perform measurements of the heat capacity as a function temperature in URu$_{2-x}$Os$_x$Si$_2$ alloys. Our experimental results show that critical second-order phase transition increases while value Sommerfeld coefficient ordered state decreases with an increase osmium concentration. also observe values at well broadening fluctuations region $x$. analyze data using Haule-Kotliar model which,...

Applications that utilize scintillation detectors at low temperatures are growing in number. Many of these require materials with high light yield and a fast response. Here we report on the low-temperature characterisation ZnSe doped Al or Te, respectively. The X-ray luminescence decay curves were measured over 77–295 K temperature range, alpha particle excitation was used to examine output kin...
