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 …
