heatWe present the specific heat measurement of the CeNi1−xCux series in a large temperature range (0.2–300 K). The high temperature measurements allow us to estimate the crystalline electric field splitting which is proximately the same for all the studied compounds, while in the low ...
If tables are not available can approximate cV by using the specific heat ratio K, which in the temperature range of 300K to 1000K, is taken to be constant (see Table A-20): Diatomic molecules K= 7/5= 1.4 (N2, O2, H2, CO, “Air”,…) ...
Electronic specific heat coefficients γ of La 1.6 xNd 0.4Sr xCuO 4 (0.0≦ x≦0.25) and La 1.9Sr 0.1Cu 1 yZn yO 4 have been extracted over the wide temperature range between 2 and 300 K, by carefully subtracting the phonon specific heat C ph from the total specific heat C. For the...
X-ray diffraction patterns taken at room temperature reveal that all compounds have the C15 cubic Laves phase structure. Heat capacity measurements have been performed in the temperature range of 2–300K without magnetic field and in a magnetic field of1 and2T. The magnetocaloric effect has been ...
Using a high resolution differential technique we have investigated from 2K and 300K the electronic and magnetic contributions to the specific heat of YBa 2 (Cu 1y Ni y ) 3 O 7 for y=0, .025, .05, .1 and .15. The initial fractional decreases per Ni in T c and the specific heat...
Heat capacityThermal expansionAntiferromagnetic transitionCrystal electric fieldThe dependencies a(T), b(T), c(T) of holmium boride clearly show a pronounced anisotropy of thermal expansion. The anomalies in the temperature changes of the HoB 50 unit cell volume at elevated temperatures are analysed ...
Heat capacity measurements on the orthorombic compounds CePt and LaPt are presented between 0.7 K and 300 K. Measurements over this large temperature range allow a good estimate of the crystalline electric field (CEF) levels derived from the J = 52 ground multiplet of the Ce 3+ ion lying ...
