An effective field theory study of layering transitions in Blume–Capel thin films in the presence of quenched random crystal fields

Yüksel, Yusuf - In: Physica A: Statistical Mechanics and its Applications 396 (2014) C, pp. 9-18

In the presence of quenched random crystal fields, phase transitions in magnetic thin films described by the spin-1 Blume–Capel model have been investigated using effective field theory (EFT). Crystal field disorder has been sampled by introducing dilute and trimodal random crystal fields. For...
