Features of Epitaxial Garnet Films for an Atomic Traps Technique

Layered Garnet Films for Applications in Atomic Traps

“…• C. During the experiments some samples appeared to be layered, this feature manifested itself in magnetooptic hysteresis loops [3].…”

“…To prevent possible errors [3] connected with comparatively small films thickness and high penetrating depth of the EDS probing (≈ 1-2 µm) the X-ray microanalysis of only GF edges was realized. On the other side, another type of error is obtained in this experimental geometry: the EDS detector signal strongly depends on the film edge surface roughness.…”

“…The procedure of thermorecording is described in [3] in detail and foresees two levels of laser beam power (λ l = 532 nm) at presence of stepped switchable homogeneous bias field. Figure 6 (left) presents non-through domain patterns thermorecorded as 2.0 µm width parallel vertical lines in the top sublayer of the double-layer film; additional local switching of the bottom layer (through--type domains) is seen as a narrow portion of the image with enhanced brightness.…”

“…Recently [2] it has been established that the GF can be the media for formation of erasable micropotentials that assist trapping of "ultracold" neutral atoms (such as 87 Rb). It was shown that some features of GF and conditions of their growth can be used to create new variants of atomic traps [3].…”
