Critical behavior and transport properties of lanthanum manganite
… Although the inverse susceptibility follows a Curie- Weiss law, it has an anomalously small slope. This is indicative of the presence of a Griffiths phase where ferromagnetic clusters emerge in a paramagnetic background well before the entire system orders. The manganites' magnetic heat …

Ionic model for chromium, manganese and iron impurities in copper
… display the normal temperature dependence of a Curie-Weiss law lead us to conclude that an ionic model of the magnetic impurity is necessary to explain the data. We develop a model which assumes a definite 3dn configuration with a definite L-S ground state and includes intraconfigurationa1 …

Magnetic properties of some niobium (IV) and tantalum (IV) complexes of distorted octahedral symmetry.
… data for all twelve complexes indicate that the Curie-Weiss law is not obeyed: Their effective moments exhibit small temperature dependence and the values at room temperature are well below the spin-only value for a single unpaired electron. Empirical fittings of mueff against kT/|lambda| curves …

Electrical and magnetic characterisation of a series of TCNQ salts.
… salts the conductivity obeys the empirical power law: [mathematical equation]. The temperature dependence of the magnetic susceptibility of all but the 1:3 salts of the isostructural series is characteristic of a system of partially localised triplet excitons. The magnitude of the singlet-triplet …

Peculiarities of crystal and magnetic structures of synthetic Co-olivine, Co 2 SiO 4
… curves above Neel temperature to the Curie-Weiss law, thus giving the Curie-Weiss temperatures and effective magnetic moments. The magnetic moments from the neutron diffraction data were found to be 3.86(5) Bohr magneton and 3.37(4) Bohr magneton for Co1 and Co2, respectively. These …
