A dysprosium based single-ion magnet is synthesized and characterized by the angular dependence of the single-crystal magnetic susceptibility. Ab initio and effective electrostatic analyses are performed using the molecular structures determined from single crystal X-ray diffraction at 20 K, 100 K and 300 K. Contrary to the common assumption, the results reveal that the structural thermal effec...

Rare earth ions play an important role in modern technology as optically active elements in solid-state luminescent materials. In many of these materials, interactions between the electronic band states of the host crystal and the rare earth ion’s localized 4f and 4f 5d states influence the optical properties of materials. This paper reports the mechanoluminescence (ML) induced by impulsive exc...

Trivalent lanthanide cations are suitable probes for Ca2+-binding sites in photosystem II (PS II). PS II membranes prepared from Nicoticinci tabacum, intact and depleted of the extrinsic polypeptides were exposed to lanthanide ions (D y3+ and Eu3+). Small concen­ trations of dysprosium and europium ions enhance oxygen evolution under short saturating flashes. Higher concentrations of the rare e...

Rare-earth elements like neodymium, terbium and dysprosium are crucial to the performance of permanent magnets used in various green-energy technologies hybrid or electric cars. To address supply risk those elements, we applied machine-learning techniques design magnetic materials with reduced neodymium content without dysprosium. However, magnet intended be motors should preserved. We develope...

Submitted for the MAR14 Meeting of The American Physical Society Synthetic gauge fields in quantum gases of dysprosium1 HUI ZHAI, Institute for Advanced Study, Tsinghua University, BENJAMIN LEV, Stanford University — To the toolbox of quantum gas-based many-body physics, highly magnetic atoms offer large, possibly non-perturbative, long-range dipolar interactions concomitant with extraordinaril...

Nd3+ or Dy3+ salts and borohydride form redox-active [Ln(BH4)4]− complexes that enable room-temperature electrodeposition of neodymium- dysprosium-containing layers from organic electrolytes.

We have developed self-propelled droplets having the abilities to detect a chemical gradient, to move toward a higher concentration of a specific metal ion (particularly the dysprosium ion), and to extract it. Such abilities rely on the high surface activity of di(2-ethylhexyl) phosphoric acid (DEHPA) in response to pH and the affinity of DEHPA for the dysprosium ion. We used two external stimu...

Four isomorphic tetranuclear lanthanide complexes, namely [Ln4(L)2(HL)2(NO3)2(OH)2](NO3)2·4H2O (Ln = Dy (1); Tb (2); Ho (3); Er (4)), constructed using hexadentate salen-type ligand N,N'-bis(3-methoxy-salicylidene)cyclohexane-1,2-diamine, have been isolated. X-ray crystallographic analysis reveals that all of the complexes 1-4 are of discrete tetranuclear structure with a unique {Ln4O8} core in...

Measurements of the relaxation rate behaviour of two series of dysprosium complexes have been performed in solution, over the field range 1.0 to 16.5 Tesla. The field dependence has been modelled using Bloch-Redfield-Wangsness theory, allowing estimates of the electronic relaxation time, T1e, and the size of the magnetic susceptibility, μeff, to be made. Changes in relaxation rate of the order ...

We observe the suppression of inelastic dipolar scattering in ultracold Fermi gases of the highly magnetic atom dysprosium: the more energy that is released, the less frequently these exothermic reactions take place, and only quantum spin statistics can explain this counterintuitive effect. Inelastic dipolar scattering in nonzero magnetic fields leads to heating or to loss of the trapped popula...
