Abstract. The aim of this review-paper is to overview high pressure techniques used in the magnetic resonances in laboratories. In this review, we would like to show the techniques that lead yielding high pressure applicable in the paramagnetic resonances. We would like to draw your attention to the separation of the effects resulting from the pressure and effects from the temperature, thereby separate the volume phonon contribution. Our main intention is to show the impact of high pressure on the structure of matter, in particular on its fundamental level.

“…The pressure is one of the most important parameters in the solid state physics because it changes the interactions between the electron spins continuously and it sometimes leads to novel physical phenomena [19][20][21][22]. Although high-pressure ESR is a powerful means to observe the spin system subjected to the pressure microscopically, it usually needs specialized equipments [10][11][12][13][14][15][16][17][18]. On the contrary, the SQUID-ESR can be applied to the high-pressure ESR very easily.…”

“…Moreover, the system can be applied to the high pressure ESR measurement without difficulty by using a piston cylinder pressure cell. This is another advantageous point as compared with other ESR systems because the high-pressure ESR usually needs specialized equipments [10][11][12][13][14][15][16][17][18]. In this paper, we show the outline of the system and its application example.…”

We have developed a high-field and high-frequency ESR system using a commercially available magnetometer equipped with the superconducting quantum interference device (SQUID). This is magnetization detection type ESR and ESR is observed as a change of the magnetization at the resonance condition under irradiation of the electromagnetic wave. The frequency range is from 70 to 315 GHz and the maximum magnetic field is 5 T. The sensitivity is estimated to be 10 13 spins/G. The advantage of this system is that the high-field ESR measurements can be made very easily and quantitatively. Moreover, this high-field ESR can be applied to the measurements under pressure by using a widely used piston-cylinder pressure cell.

The performance of new dielectric ceramic resonators (DRs) for continuous wave (cw) X-band electron paramagnetic resonance (EPR) spectroscopy is investigated at room temperature and low temperatures (77, 6 K). The DRs with high dielectric constants of about e r ¼ 80, featuring low residual paramagnetic impurities, have been developed and produced on the basis of barium lanthanide titanates solid solutions with the general formula Ba 6Àx Ln 8þ2x=3 Ti 18 O 54 (Ln = Sm, Nd) that demonstrate at once low dielectric losses in the microwave range (tan d ¼ 7-14 9 10 -4 at 10 GHz) and appropriate temperature stability of the dielectric constant (s e ¼ AE5 ppm/K). They were optimized for samples with small dimensions and can be used in commercial Oxford instruments flow cryostats if the coupling is done via cavity resonators. We found a maximal EPR signal enhancement by a factor up to 74 at 6 K. The increases of quality and filling factors as well as that of the microwave (mw) B 1 -field in the resonator setup are discussed in dependence on temperature. We show that the absolute sensitivity gain must be related to that increase in the mw field and the remaining relative gain of the SNR is Electronic supplementary material The online version of this article (Applied Magnetic Resonanceabout 18 for small samples. The developed DRs have shown a good potential in EPR application as reliable and easy-to-use components allowing research of thin films and in particular small crystalline structures.
