The susceptibility and specific heat experimental results of the diluted magnetic semiconductors (DMS) are incorporated in a model based on short-range as well as long-range interaction in a random may of magnetic ions. The so-called nearestneighbor pair approximation (NNPA) is applied. It appears that the calculated values of zero field specific heat and Curie-Weiss temperature based on th...

The magnetic properties of uncoated, epitaxial Tb(0001) films on W(110) substrates are studied using electron capture spectroscopy. The topmost layer orders ferromagnetically below a surface Curie temperature Tc. = 249.96 f 0.02 K, which lies above the bulk Curie and NCI temperatures Tcb=220 K and TNb = 228 K. Near Tcs, novel critical behavior is observed, suggesting the existence of strong sur...

Thin films of ferroelectric strontium-doped lead zirconate titanate [PSZT, (Pb(0.92)Sr(0.08))(Zr(0.65)Ti(0.35))O(3)] deposited by RF magnetron sputtering have been analyzed by in situ analysis techniques. The in situ techniques employed for this study include micro-Raman spectroscopy and X-ray diffraction (XRD), and variations in thin film structure and orientations for temperatures up to 350 d...
