potential field methods such as gravity and magnetic methods are among the most applied geophysical methods in mineral exploration. a high-resolution technique is developed to image geologic boundaries such as contacts and faults. potential field derivatives are the basis of many interpretation techniques. in boundary detection, the analytic signal quantity is defined by combining the val...

We report the single crystal growth and anisotropic magnetic properties of the tetragonal RAg2Ge2 (R = Pr, Nd and Sm) compounds which crystallize in the ThCr2Si2 type crystal structure with the space group I4/mmm. The single crystals of RAg2Ge2 (R = Pr, Nd and Sm) were grown by self-flux method using Ag:Ge binary alloy as flux. From the magnetic studies on single crystalline samples we have fou...

Electronic transport in ferromagnetic ballistic conductors is predicted to exhibit ballistic anisotropic magnetoresistance-a change in the ballistic conductance with the direction of magnetization. This phenomenon originates from the effect of the spin-orbit interaction on the electronic band structure which leads to a change in the number of bands crossing the Fermi energy when the magnetizati...

Late Precambrian to early Cambrian sediments of the Amadeus Basin, Central Australia, contain two stable directions of magnetization. Lithologies are diverse and include red beds, green beds, and carbonates, all of which respond to thermal cleaning. Positive fold and unconformity tests, and a well-defined polarity zonation reveal the primary component and direction of magnetization. This direct...

The irreversible thermodynamics of a continuous medium with magnetic dipoles predicts that a temperature gradient in the presence of magnetization waves induces a magnetic induction field, which is the magnetic analog of the Seebeck effect. This thermal gradient modulates the precession and relaxation. The magnetic Seebeck effect implies that magnetization waves propagating in the direction of ...

Inversion of magnetic data has long been hampered by the need to specify the direction of magnetization. We present a general approach that utilizes the minimal dependence on magnetization direction of amplitude and total gradient data and thereby overcome the difficulty associated with inversion when unknown remanent magnetization is present. To construct the inversion algorithm for the magnit...

Fast strain wave induced magnetization changes in long cobalt bars: Domain motion versus coherent rotation" (2015). A high frequency (88 MHz) traveling strain wave on a piezoelectric substrate is shown to change the magnetization direction in 40 lm wide Co bars with an aspect ratio of 10 3. The rapidly alternating strain wave rotates the magnetization away from the long axis into the short axis...
