Strain Fields and Critical Phenomena in Manganites II: Spin-Lattice-Energy Hamiltonians
Rohit Singh, Sanjay Puri
The dynamic critical behavior at the paramagnetic-antiferromagnetic (PM-AFM) transition in manganites has recently been studied experimentally [Niermann et al., Phys. Rev. Lett. {\…

Strain Fields and Critical Phenomena in Manganites I: Spin-Lattice Hamiltonians
Rohit Singh, Sanjay Puri
We use a model Hamiltonian to study critical phenomena in manganites. This Hamiltonian includes long-range strain interactions, and a coupling between the magnetic order parameter…
