D to F is a minor third (3 semitones), F to A is a major third (4 semitones), A to C# is a major third (4 semitones). A minor triad with a major seventh, C#, a half step below the root. The minor third F and the major seventh make an augmented triad (F A C#) inside the chord, which gives it its tense, suspenseful sound.

The E-shape and A-shape grips are movable: an E-shape chord's root is the note under your first finger on the low E string, an A-shape chord's root is the note on the A string. Slide the same grip up or down to play minor-major seventh chords on other roots.

Inversions of Dm(maj7)

An inversion puts a note other than the root in the bass. The name is what semicord's chord finder calls those notes played bottom to top; a slash name like C/E means a C chord with E in the bass.

Where Dm(maj7) fits

Dm(maj7) is i(maj7) in D minor. Most often it is a passing chord in the descending line Dm → Dm(maj7) → Dm7 → Dm6, where one voice falls a half step at a time from D. The first four bars of the jazz standard "My Funny Valentine" (Cm, Cm(maj7), Cm7, Cm6 in C minor) are exactly that line.
