摘要：

The critical behavior of bi-skyrmion host centrosymmetric bi-layer manganite La1.37Sr1.63Mn2O7 has been explored and found that it exhibits second-order magnetic phase transition. The critical exponents have been determined using different methods and found to satisfy the Widom and Rushbrooke scaling relations. The critical exponents are compatible with 2D-Ising universality class, which suggests that anisotropy in bi-layer La1.37Sr1.63Mn2O7 due to its layered structure plays a crucial role. Further, we have presented a possible magnetic phase diagram of the bi-skyrmion host bi-layer La1.37Sr1.63Mn2O7.
