Polarizable diamond materials and methods for obtaining nuclear magnetic resonance spectra of samples external to the diamond materials are described. The diamond materials can include .sup.12C, .sup.13C, substitutional nitrogen, and nitrogen vacancy defects in a crystalline lattice, wherein the substitutional nitrogen concentration is between 10 ppm and 200 ppm, the nitrogen vacancy concentration is between 10 ppb and 10 ppm, and the .sup.13C concentration is greater than 1.1% and not more than 25%. Methods for obtaining nuclear magnetic resonance spectra can include optically pumping a diamond material to generate electron spin hyperpolarization in nitrogen vacancy centers, transferring the electron spin hyperpolarization to nuclei of the sample, and generating a nuclear magnetic resonance spectrum by applying a magnetic field to the sample, exciting the sample with a radio frequency pulse, and detecting a nuclear magnetic resonance response from the sample.

Introduced here is an electromechanical actuator that includes a stator assembly with a chamber partially defined therethrough along a central longitudinal axis and a plunger assembly that is situated in the chamber and, in operation, moves along the central longitudinal axis between different positions. The stator assembly can include a pair of contacts that have an opening therebetween and a trinity of ferromagnetic layers with coils situated therebetween. The plunger assembly can include a magnet. When current is applied to the coils, the trinity of ferromagnetic layers become magnetically polarized, thereby dictating the motion of the plunger assembly by magnetically attracting or repelling the magnet included in the plunger assembly. The plunger assembly may be stabilized by a flexure flexibly connecting the stator assembly and plunger assembly.
