New Methods for Critical Analysis: Revealing the Simultaneous Existence of Universality Classes in Nontrivial Magnetic Systems
Harish Chandr Chauhan, Umesh C. Roy, Shovan Dan +2
In magnetic systems, the microscopic constituents exhibit power law behavior near the paramagnetic transition temperature, . The critical exponents (CEs) associated with the p…
