A ferromagnetic intramolecular dipolar interaction is observed and verified by both experimental studies and ab initio calculations on a dinuclear holmium(III) complex [Ho2(H2cht)2Cl4(H2O)(MeCN)]·MeCN.
Resonant magnetic X-ray scattering (RMXS) experiments at the Ho-L3 and M5 thresholds have been performed on thin holmium-metal films grown in situ in ultra-high vacuum on W(110). The experimental set-up for these experiments as well as results for the magnetic structure of these films will be described. The magnetic structure stays bulk-like down to a thickness of 14 monolayers.
What is the evidence base for this information? This publication includes advice from consensus panels, the British Association of Urological Surgeons, the Department of Health and evidence-based sources. It is, therefore, a reflection of best urological practice in the UK. It is intended to supplement any advice you may already have been given by your GP or other healthcare professionals. Alte...
Nanoparticles where holmium was substituted with nickel-cadmium Ni0.5Cd0.5HoxFe2-xO4 (X = 0, 0.02, and 0.04) ferrites were synthesized through a sol-gel auto-combustion process to reveal their structural physical properties. The nanoparticles characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared ray (FTIR) spectroscopy, impedance spectroscop...
Abstract The heat capacity of bismuth cobalt oxides doped by neodymium and holmium was measured for the first time differential scanning calorimetry in temperature range 319-1000 K.
We discuss a method for scaling a neutral-atom Rydberg gate quantum processor to a large number of qubits. Limits are derived showing that the number of qubits that can be directly connected by entangling gates with errors at the 10−3 level using long-range Rydberg interactions between sites in an optical lattice, without mechanical motion or swap chains, is about 500 in two dimensions and 7500...
In the dynamic nuclear polarization process, microwave irradiation facilitates exchange of polarization from a radical's unpaired electron to nuclear spins at cryogenic temperatures, increasing polarization by >10,000. Doping samples with Gd(3+) ions further increases the achievable solid-state polarization. However, on dissolution, paramagnetic lanthanide metals can be potent relaxation agents...
We take another look at two compounds which have been discussed as possible realizations of ‘‘spin ice,’’ namely holmium titanate and dysprosium titanate. As we have earlier observed, holmium titanate does not display icelike behavior at low temperatures because the long-ranged dipolar interactions between spins are strong compared to the nearest-neighbor interactions. We show, exactly, that th...
A nanoparticle (NP) doping technique was developed for fabricating erbium (Er)- and holmium (Ho)-doped silica-based optical fibers for high energy lasers. Slope efficiencies in excess of 74% were realized for Er NP doping in a single mode fiber based master oscillator power amplifier (MOPA) and 53% with multi-Watt-level output in a resonantly cladding-pumped power oscillator laser configuration...
BACKGROUND In 1996, Holmium laser enucleation of the prostate was introduced and has been shown to be safe and highly effective. CASE PRESENTATION We report a case of a rare complication that resulted in intra-abdominal compartment syndrome with prolonged intubation and intensive care, involving an 74-year-old male after holmium laser enucleation of prostate, with a massive irrigant fluid lea...
