Probe–Sample Coupling in the Magnetic Resonance Force Microscope
Journal of Magnetic Resonance, 2002The magnetic resonance force microscope (MRFM) provides a route to achieving scanned probe magnetic resonance imaging with extremely high spatial resolution. Achieving this capability will require understanding the force exerted on a microscopic magnetic probe by a spatially extended sample over which the probe is scanned.

Double Magnetic Resonance of Coupled Spins
Journal of Applied Physics, 1967A perturbation procedure is introduced to solve for the probability amplitudes of a system of coupled spins under the action of two rf magnetic fields; one a large saturating signal, the other a relatively weak one. The power absorbed when the saturating signal connects two states in the system is affected by the presence of the second signal ...

A Note on the Magnetic Resonance of Coupled Spin Systems
Journal of the Physical Society of Japan, 1964The magnetic resonance of a coupled spin system is considered phenomenologically. The magnetic resonance modes can be directly determined from the irreducible representations of the space group to which the system belongs. Then, approximate calculation of the frequency and intensity of resonance lines can be made. This approach is convenient especially

Strongly coupled resonance magnetic for RFID applications
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013Wireless power and data transfer (WPDT) through the strongly coupled magnetic resonance (SCMR) method at an RFID frequency is reported. The proposed system consists of four single resonant loops, in contrast to the two resonant loops traditionally used in RFID.

Magnetically coupled resonators for rate integrating gyroscopes
IEEE SENSORS 2014 Proceedings, 2014This work demonstrates for the first time the use of magnetic field to couple mechanical resonators that can be separated by long distances (8mm in this work) compared to coulombic/electrostatic coupling (~ 1 nm – 1 μm depending on the surface charge density or E-field).

Coupling of geminal protons in nuclear magnetic resonance
Chemical Physics Letters, 1972Abstract The JHHgem coupling constants of six polyatomic molecules were calculated ab initio by the double perturbation method in a basis of localized SCF orbitals. Leading terms of different orders were retained. The agreement with experimental values is satisfactory.

Investigation of Magnetic Coupling by Ferromagnetic Resonance
2004Ferromagnetic Resonance (FMR) is a powerful method for study the magnetic coupling in multilayers. In the present work, a trilayer system is assumed to be characterized by the bilinear J 1 , biquadratic J 2 coupling, and in-plane uniaxial magneto-crystalline anisotropies with anisotropy axis directions in the two layers making a δ angle.
