Role of external and internal perturbations on ferromagnetic phase transitions in manganites: Existence of tricritical points
Prabir K Mukherjee, Prosenjit Sarkar, Amit K Chattopadhyay
A phenomenological mean-field theory is presented to describe the role of external magnetic field, pressure and chemical substitution on the nature of ferromagnetic (FM) to paramag…
