## Executive Summary
* Investigates magneto-electro-elastic effects in diamond containing negatively charged nitrogen-vacancy (NV) centers.* Predicts that external electric fields or strains can induce magnetic moment projections perpendicular to an applied magnetic field.* Demonstrates how NV center spins contribute to the anisotropy of diamond's electric permittivity, dependent on magnetic field and temperature.* Calculates temperature and magnetic field-dependent renormalization of diamond's elastic moduli due to NV center spin quadrupole moments.* Highlights the potential of these effects for local sensing applications using diamond nanocrystals in nanoelectronics.* Analyzes the impact of external stimuli on the magnetic response and elastic/electric characteristics of diamond nanocrystals.

Characteristics of magneto-electro-elastic effects in a diamond with negatively charged nitrogen vacancy centers are calculated analytically. It is predicted that strains or the external electric field can cause the onset of projections of the magnetic moment of those vacancies perpendicular to the applied magnetic field. It is shown how spins of those vacancies produce the anisotropy of the electric permittivity of a diamond, which depends on the external magnetic field and temperature. The temperature- and magnetic-field-dependent renormalization of elastic modules of a diamond caused by spin quadrupole moments of negatively charged nitrogen vacancy centers is calculated. The predicted effects can be important in the practical use of diamond nanocrystals with color vacancies as local sensors in modern nanoelectroncs.
