High-efficiency magnetic refrigeration using holmium

Feb 19, 2021  Most research to date has employed high magnetic fields (at least 5 T) to obtain a large entropy change, which requires a superconducting magnet and, therefore, incurs a large energy cost. Here we propose an alternative highly efficient cooling technique in which small magnetic field changes, Δμ 0 HS M /Δμ 0 H = 32 J kg −1 K −1 T −1 ...

Efficient magnetic-coupling excitation of LSSPs on high-Q ...

In summary, a series of high-Q multilayer planar-circular-grating resonators was designed, and an efficient magnetic-coupling method to excite LSSPs was proposed for the first time. Experiments showed that Q-factors were doubled to more than 200 by suppressing material loss as well as radiation loss, exceeding almost all previous studies.

Efficient magnetic-coupling excitation of LSSPs on high-Q ...

Jul 22, 2021  Recently, ultrathin localized spoof surface plasmon (LSSP) resonators are found to have intrinsic defects of relatively low quality factors (Q-factors) because of unavoidable material and radiation losses. In this paper, multilayer structures of planar-circular-grating resonators and their magnetic-coupling schemes are proposed to achieve effective excitation of high-Q LSSPs modes.
