Natterer and colleagues created the minuscule magnetic bits using atoms
of holmium deposited on a surface of magnesium oxide.
Both studies examine the magnetic behavior of a family of rare - earth materials known as spin ices — one group using
holmium titanate and the other dysprosium titanate.
With the help of STM, they built and measured the isolated single atom bits
using holmium atoms.
The French - led team experimented
with holmium titanate and the Germany - based group, dysprosium titanate.
Three of those elements — ytterbium, erbium, and terbium — were simply given additional variants on the name of Ytterby, while the other three were
named holmium (for Stockholm), scandium, and thulium (both from the Latin for Scandinavia), in the nationalistic fashion then in favor.
Microbrachytherapy involves injecting a small amount of
radioactive holmium - 166 directly into the tumor.
ATOMIC BIT Scientists stored data using individual atoms
of holmium (shown above).
A special laser, called
a holmium: YAG laser, is used to break up the stone and endoscopy is needed to get the laser right up to the stone where the patient's tissues are not in the way.
A specific type of laser called
a holmium: YAG laser, is used to break up the stone and endoscopy is needed to get the laser right up to the stone where the patient's tissues are not in the way.
The most commonly used apparatus is
a holmium YAG laser.
