Magnetic Materials: Fundamentals and Device Applications
Therefore if a paramagnet is cooled to liquid helium temperature in the presence
of a strong magnetic field, the magnetization is nearly saturated, so most of the
spins are lined up parallel to the field. If the paramagnet is then thermally isolated
...

Registration of stable signal of EPR in solution does not mean, of course, that
chemically pure paramagnet can be separated out of it, the particle structure of
which corresponds to the structure of non-solvated free radicals. Moreover it's not

The Mn(TCNE)xy(CH2Cl2) is a reentrant spin glass (paramagnet (PM) — >
ferromagnet (FM) — > spin glass (SG) with decreasing temperature). The
transition temperatures are Tc = 75K and Tg < 10K. The Fe(TCNE)xy(CH2CI2) is
a double ...

Introduction to Frustrated Magnetism: Materials, ...
The quadratic dependence of F on M shows that the paramagnet resists
magnetization in the absence of an applied field. This resistance is purely
statistical or entropic as there is no energetic penalty in magnetizing a
paramagnet: it doesn't ...

... Figure 17.16 shows a system in which there is no significant interaction at all
among the magnetic centers; instead, all spins are randomly oriented and rapidly
re-orienting. Such a structure is a paramagnet, and it possesses no net moment.

Equilibrium Thermodynamics
we should expect from the connection between entropy and order, for the
magnetization of a paramagnet increases the magnetic ordering and thus
decreases the magnetic contribution to the entropy. In an isothermal change,
heat will ...

The New Physics: For the Twenty-First Century
So there must be at least one quantum phase transition at some intermediate δ at
which the anti- ferromagnetic arrangement of magnetic moments in La2CuO4 is
destroyed: this is the antiferromagnet–paramagnet quantum transition.

Nano-Semiconductors: Devices and Technology
In Equation 4.2, J↑(J↓) represents the current carried by the majority (minority)
spin species in the paramagnet, immediately after spin injection. If the
paramagnet is a tunnel barrier then the spin polarization of the tunneling current (
i.e., η) can ...
