Abstract(J)磁気冷凍法は物質が示す磁気熱量効果を用いた冷凍法であり、水素を効率的に冷却する手段として水素社会への期待されている。その実現には高い磁気熱量効果を示す物質開発が欠かせない。我々は機械学習を用いることでそのような物質を効率的に見出すことに成功したので、本稿にてその経緯を紹介する。

Abstract(E)Magnetic refrigeration, that exploits the magnetocaloric effect of the materials, is expected to play an important role for cooling hydrogen down to its liquefaction temperature with high efficiency. Here, we report our machine-learning aided approach to find experimentally a material showing a marked magnetocaloric effect near the liquefaction temperature of hydrogen.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
