Thermal expansion studies on the unusual first order transition of Gd5Si2 09Ge1 91: effects of purity of Gd
... Two polycrystalline samples were made by using high purity Gd and commercial Gd, respectively, but with Si and Ge starting materials of the same purity in both cases. Thermal expansion results showed that both samples ...

Crossover from first-to-second-order ferromagnetic transition in narrowband manganite Sm1-xSrxMnO3 (x = 0.48)
... PM transition in SSMO is first order in nature in the low-field regime, which gets weakened at high fields, as clearly reflected by the suppression of the discontinuity in ρ, M, and Q at the ...
