Magnesioferrita e caminho pedogenético de transformação de óxidos de ferro magnéticos em dois perfis de solo derivados de tufito da região do Alto Paranaíba (MG) Magnesioferrite and pedogenetic transformation pathway of magnetic iron oxides in two soil profiles developing on tuffite of the Alto Paranaíba region, state of Minas Gerais, Brazil

Revista Brasileira de Ciência do Solo, 2005
Solos magnéticos derivados de tufito da região do Alto Paranaíba (MG) têm mineralogia bastante variável, mas são relativamente ricos em óxidos de Fe isoestruturais ao espinélio, mais especificamente: (Ti, Mg)-magnetita e (Ti, Mg)-maghemita.

Switching dynamics between metastable ordered magnetic state and nonmagnetic ground state - A possible mechanism for photoinduced ferromagnetism -

, 1998
By studying the dynamics of the metastable magnetization of a statistical mechanical model we propose a switching mechanism of photoinduced magnetization.

Inducing Chirality and Chiral Instabilities in Ferrogels with Homogenous Magnetic Fields

Advanced Functional Materials, EarlyView.
By pre‐aligning magnetic particles into chains, significant chiral deformations are induced by fixing the base of a cylindrical actuator and applying a homogeneous magnetic field. Subsequent base rotation can drive the system into metastable states. Further rotation or reduction of field strength triggers a chiral instability, characterized by a switch

Remarks on the Quantum Effects of Screw Dislocation Topology and Missing Magnetic Flux

Condensed Matter
We revisit the interaction between a point charge and an inhomogeneous magnetic field that yields the magnetic quantum dot system. This magnetic field is defined by filling the whole space, except for a region of radius r0.

Numerical study of magnetization processes in rare-earth tetraborides

, 2010
We present a simple model for a description of magnetization processes in rare-earth tetraborides. The model is based on the coexistence of two subsystems, and namely, the spin subsystem described by the Ising model and the electronic subsystem described
