Modeling Molecular Magnets with Large Exchange and On-Site Anisotropies
Sumit Haldar, Rajamani Raghunathan, Jean-Pascal Sutter +1
Spins in molecular magnets can experience both anisotropic exchange interactions and on-site magnetic anisotropy. In this paper we study the effect of exchange anisotropy on the mo…
Modeling Magnetic Anisotropy of Single Chain Magnets in Regime
Sumit Haldar, Rajamani Raghunathan, Jean-Pascal Sutter +1
Single molecule magnets (SMMs) with single-ion anisotropies , comparable to exchange interactions J, between spins have recently been synthesized. In this paper, we prov…
Study of Low Temperature Magnetic Properties of a Single Chain Magnet With Alternate Isotropic and Non-Collinear Anisotropic Units
Shaon Sahoo, Jean-Pascal Sutter, S. Ramasesha
Here we study thermodynamic properties of an important class of single-chain magnets (SCMs), where alternate units are isotropic and anisotropic with anisotropy axes being non-coll…
Microscopic Model for High-spin vs. Low-spin ground state in () magnetic clusters
Rajamani Raghunathan, Jean-Pascal Sutter, Laurent Ducasse +2
Conventional superexchange rules predict ferromagnetic exchange interaction between Ni(II) and M (M=Mo(V), W(V), Nb(IV)). Recent experiments show that in some systems this superexc…
