• Use these formats for best results: Smith or J Smith
• Use a comma to separate multiple people: J Smith, RL Jones, Macarthur

Tips for preparing a search:

Keep it simple - don't use too many different parameters.
Separate search groups with parentheses and Booleans. Note the Boolean sign must be in upper-case.
- Example: (diode OR solid-state) AND laser [search contains "diode" or "solid-state" and laser]
- Example: (photons AND downconversion) - pump [search contains both "photons" and "downconversion" but not "pump"]
Improve efficiency in your search by using wildcards.

Asterisk ( * ) -- Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity"
Question mark (?) -- Example: "gr?y" retrieves documents containing "grey" or "gray"

Use quotation marks " " around specific phrases where you want the entire phrase only.
For best results, use the separate Authors field to search for author names.
Author name searching:
- Use these formats for best results: Smith or J Smith
- Use a comma to separate multiple people: J Smith, RL Jones, Macarthur
- Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.

Abstract

Abstract

We investigated the effect of an Al underlayer thickness from the viewpoint of a read/write performance. We found that even a 1 nm Al underlayer induces magnetic pinning sites which improve the high-density recording capability.
