Frustration effects inmagneticmolecules
By means of exact diagonalization we study the ground-state and the low-temperature physics of the Heisenberg antiferromagnet on the cuboctahedron and the icosidodecahedron. Both are frustrated magnetic polytopes and correspond to the arrangement of magnetic atoms in the magnetic molecules Cu12La8 and Mo72Fe30. The interplay of strong quantum fluctuations and frustration influences the ground s...
متن کاملFrustration effects in magnetic molecules
Besides being a fascinating class of new materials, magnetic molecules provide the opportunity to study concepts of condensed matter physics in zero dimensions. This contribution will exemplify the impact of molecular magnetism on concepts of frustrated spin systems. We will discuss spin rings and the unexpected rules that govern their low-energy behavior. Rotational bands, which are experiment...
متن کاملPhytochemicals Targeting Estrogen Receptors: Beneficial Rather Than Adverse Effects?
In mammals, the effects of estrogen are mainly mediated by two different estrogen receptors, ERα and ERβ. These proteins are members of the nuclear receptor family, characterized by distinct structural and functional domains, and participate in the regulation of different biological processes, including cell growth, survival and differentiation. The two estrogen receptor (ER) subtypes are gener...
متن کاملFrustration effects in antiferromagnetic molecules: the cuboctahedron
Frustration of magnetic systems which is caused by competing interactions is the driving force of several unusual phenomena such as plateaus and jumps of the magnetization curve as well as of unusual energy spectra with for instance many singlet levels below the first triplet state. The antiferromagnetic cuboctahedron can serve as a paradigmatic example of certain frustrated antiferromagnets. I...
متن کاملDeprenyl Can Mediate Neuronal Protection Rather than Neuronal Rescue
Background and Objective: Deprenyl is a drug for the treatment of Parkinson’s disease, where the dopaminergic neurons are the target of this drug. Several reports also documented that deprenyl has an effect on the sensory and motor neurons. There are some reports about the mode of action of deprenyl on m...
